摘要

Histogram modification (HM) is an efficient algorithm for reversible data hiding into H.264 video, motion vector based methods have been applied to HM. In this paper, we present a special strategy of reversible data hiding using motion vector based on two-dimensional histogram modification. Firstly, the two components of a motion vector will compose an embedding pair. The values of embedding pairs are classified into 17 non-intersect sets. Then, according to the set that the embedding pair belongs to, we can embed data into motion vectors by modifying the value of embedding pair. Experimental results verify that the embedding capacity is increased by two times compared with the previous algorithm, and the PSNR declines about 5%. The reversibility of the algorithm is also studied, three rules are presented to judge the reversibility of an algorithm directly, and the rules are suitable for other histogram modification based methods.
